Radiology Cases of Uterus Under Maternal Stimulation of Estrogen
Transverse US of the pelvis shows the fluid-filled bladder on the anterior right side of the image with a uterus with a thickened myometrium and prominent central endometrial stripe located just posterior to it. A large anechoic structure without septations is seen in the left side of the image and was felt to be associated with the right ovary.
